Execution:
- Patient is in supine lying position and the examiner is standing on the asymptomatic side
- The examiner flexes the patient’s hip to 90° and places one hand under the patient’s sacrum
- Afterwards, the examiner applies longitudinal pressure through the patient’s femur (which is slightly horizontally adducted) with 3-6 higher velocity thrusts of gradually increasing pressure
Positive Outcome: Patient’s familiar pain (usually in the buttock, lower lumbar spine, posterolateral thigh and groin) is reproduced

| Comment: The Distraction Test is the most sensitive test in the Cluster of Laslett (see below). Performed without the hand under the sacrum and increasing pressure instead of thrusts in the Cluster of van der Wurff | |||||
